1 Samuel 24:1-4
David refuses to kill Saul
1 When Saul had finished fighting against the Philistines, he returned to his home. Someone told him that David was in the desert at En Gedi. 2 So Saul chose 3,000 of the best soldiers in Israel. They went to look for David and his men near Wild Goat Rocks.
3 Saul came to the place near the road where the shepherds keep their sheep. There was a cave near to this place. Saul went in there to use it as a toilet.
David and his men were hiding at the back of the same cave. 4 David's men said to him, ‘This is the day that the Lord told you about! The Lord said to you, “I will give your enemy to you. Then you can decide what is the right thing to do to him.” ’ So David stood up very quietly. He went and he cut off a small piece of cloth from Saul's coat. Saul did not know what had happened.
